So, digging further - hadoop seems to want to create a file
<mapred.system.dir>/<job id>/jobToken
for each job I submit.
I assume this file is related to the new security stuff. Can I disable
this activity until I require the security functionality or can I get
this file created somewhere else?
Or should the permissions enforced by the JobTracker on
mapred.system.dir be changed if this is always required?
I've explicitly set the following
<property>
<name>hadoop.security.authorization</name>
<value>false</value>
</property>
<property>
<name>hadoop.security.authentication</name>
<value>simple</value>
</property>
and the jobToken file is still created so every-user seems to need
access to this directory.
Should I open a bug about this behaviour or is what I'm trying to do
unsupported?
